Application flled April 28, 1925. Serial No. 26,8.

This invention relates to radiator caps or closure devices for automobile radiators or the like, and more particularly to radiator caps of the bar type which heretofore have been made of castings which are relatively expensive in initial cost and require the exnditure of a great deal of time and labor 1n the finishing.

The objects of the present invention are to provide a radiator cap of the so-called bar type of very simple construction and which is relatively light in weight 'and inexpensive to produce. Further-comets are to provide a radiator cap, the principal ItlOIlS of 7 or closure device embodying the invention.

Fig. 2 is a longitudinal sectional elevation thereof on line 22, Fig. 3.

Fig. 3 is a bottom plan view thereof.

Fig. 4 is a plan view of the frame member of the device, with the cap member omitted.

Fi 5 is'a bottom plan view of the cap mem r before being attached to the frame member.

Accor to the present invention, instead of constructing the radiator cap of one or more pieces of cast metal, the cap of the present invention is preferably made as folows:

There is provided a cup or closure member which is formed with an annular portion 11 provided with threads 12 adapted to engage the threads on the usual collar (not shown) of the radiator. The cap also has a to closed portion of any suitable outline, such Figs. 1 and 2. This top is so formed as to leave a shoulder15 extending beyond the annular portion 11.

The cap may be made of any suitable material, and the top 14 thereof may be nickel plated or provided with any desirable or attractive finish. The device further includes.

a frame or frame'member 16 having a pair of horizontal, lateral, channeled arms 17 i and a central annular or ring portion 18 which is complementary to the portion 11 of the cap. The frame member 16 may be readily stamped from suitable material such,

as the annular top portion 14, see

Suitable and novel means are. provided for connecting the frame member 16 'to the ca or cup 10. In the form shown, the cap 1s provided wlth In S or parts 19 which, when the cup member 1s formed, extend laterally from the lower edge of the annular portion 11 at diametrically opposite sides of the cup.

In assembling the device,'-the ca portion llis press fitted into the centre annular portion 18 of the frame until the shoulder 15 engages the top edge of said portion 18,

and the lugs 19 are then bent to extend up-' wardly between the sides of the channels 17 of the frame, as shown in Fig. 2. When thus assembled the ends of the lugs 19 engage the under side of the channel webs of t e arms 17 and prevent separation of or relative rotary movements between the cap and frame member.

The caps may be readily formed of any suitable metal'such for example as brass, ina minimum number of stamping operations, and the frame members may be readstamped in large quantities from any i1 cl ihap metal and given a suitable finish, and when the parts are a embled as described,

a neat and attractivyarticle results.

I claim as my invention: I

1. A; radiator cap comprising a frame member-having handle portions thereon, a

cap member having parts for engaging parts of a collar surrounding the radiator opening, one member having a recess and a lug projecting from the other member and bent backwardly thereover to form an outstanding shoulderextending into the recess for maintaining said frame member connected to said cap member and preventing relative movements therebetween.

2. In a radiator cap, a cap portion having parts for engaging the collar surrounding the opening through a radiator for closing said opening, a sheet metal, stamped frame member recelving said cap portion, and interengaging parts on said frame member and said cap at diametrically opposite points on the periphery of the latter whereby said frame member is maintained connected to said cap.

3. In a radiator cap, a cap portion having parts for engaging parts of a collar surrounding the radiator opening, and a stamped sheet metal frame member having for example, as sheet steel or other metal. a central opening receiving said cap porm tion, the wall of said frame member opening being interlocked with said cap member.

4. In a radiator cap, a cap member having parts for engaging parts of a collar surrounding the radiator openmg, a stamped sheet metal frame member having a central opening receiving said cap member, and bendable means on one of said members for interlocking the two members together against relative rotation.

5. in a radiator cap, a metal frame memher having acentral portion and side portions projecting from said central portion, said side portions being in the form of channels opening downwardly, a cap member carried by said central portion for closing the opening through a collar on a radiator, and parts on said cap member extending into said channels and engaging the side walls of said channels for preventing relative rotation between said frame member and said cap.

6a in a radiator cap for automobiles and the like, a stamped metal frame member having a central portion and oppositely extending arms in the form of channels opening downwardly, a cap member carried by the central portion of said frame and adapted to close the opening through a collar on the automobile radiator, lugs on said cap member engaging said frame member and extending into the channels of said side arms for preventing relative rotation between said cap member and said frame member. i

LA radiator cap comprising a frame member consisting of a cylindrical portion and a handle portion extending outwardly therefrom, and a cap member receivable by and seating on the upper side of said cylindrical portion and having a common means interlocking-with and engaging the under side of said frame member for securing said cap member both against displacement from and against rotation on said frame member.

8. A radiator cap comprising aframe member consisting of a cylindrical portion having outwardly extending recessed handles, a cap member seating on the cylindrical portion of said frame member and having a part fitting within the same, and means for interlocking said part to said hand grip portion, said frame member, said means engaging in the recesses of said handles.

9. A radiator cap comprisin an annular frame member having outwar 1y extending handles provided with recesses opening through said annular frame member, and a cap member seating upon said annular frame member and having a part extending therewithingi said part carrying means adapted to be moved outwardly into the handle recesses for interlockin'g said members together. I

l 10. A,radiator cap comprising an annir,

lar frame member having outwardly ex tending handles provided with recesses opening through said annular frame mem her, and a cap member seating upon said annular frame member and having a cylindrical part fitting therein, the free edge of said cylindrical part having lugs adapted to be bent outwardly and upwardly into the sheet metal frame having'an annular por-' tion. and. outwardly extending channeled handles, a cap member having a peripheral shoulder set on said annular portion and a part bendable out into the channels of the handles for interlocking the two members together.

13. A two part radiator cap, comprising in its entirety, an integral closure member, and an. integral frame member havin a closure mem ber havin an annular portion embraced by said rame member, one of said members having an open bottomed recess and the other of said members having a'projecting lug bent backwardly onto its member to form a shoulder for engaging in the recess to interlock the two members together, said lug being accessible throughthe open bot tom of the recess.
